i've posted many many quilts over the past couple years here on the board- pretty much all of them combine batiks, cottons, flannels, wools, silks....you've seen lots of pictures of them- just didn't know that they had a variety of fabrics in them...i see quilts with batiks (which are 100% cotton) and other fabrics all the time- in fact very seldom do i see a quilt that is all batiks.
